Before this patch the owner field of the /dev/radio# device fops was set to
the snd-tea575x-tuner module itself. Meaning that the module which was using
it could be rmmod-ed while the device is open, and then BAD things happen.

I know, as I found out the hard way :)

Note that there is no need to also somehow increase the refcount of the
snd-tea575x-tuner module itself, since any drivers using it will have
symbolic references to it.

Yuck. The VIDIOC_(TRY_)DECODER_CMD ioctls already had ioctl numbers 96 and 97,
and after merging the timings API I forgot to continue numbering from 98. So
now we have two ioctls with number 96 and two with 97.

With the new table-driver ioctl handling in v4l2-ioctl.c it is essential that
each ioctl has its own unique number, so let's fix this quickly for 3.5.

There is getting more entities to manage within single video pipeline
in newer SoCs. To simplify code put subdevs' pointer into an array
rather than adding new member in struct fimc_pipeline for each subdev.
This allows to easier handle subdev operations in proper order.

Additionally walk graph in one direction only in fimc_pipeline_prepare()
function to make sure we properly gather only media entities that below
to single data pipeline. This avoids wrong initialization in case where,
for example there are multiple active links from s5p-mipi-csis subdev
output pad.

struct fimc_pipeline declaration is moved to the driver's public header
to allow other drivers to reuse the fimc-lite driver added in subsequent
patches.

If the V4L2_EVENT_SUB_FL_SEND_INITIAL was set, then the application expects
to receive an initial event of the initial value of the control.

However, commit c53c2549 that added the new
v4l2_subscribed_event_ops introduced a regression: while the code still queued
that initial event the __v4l2_event_queue_fh() function was modified to ignore
such requests if sev->elems was 0 (meaning that the event subscription wasn't
finished yet).

And sev->elems was only set to a non-zero value after the add operation
returned.

This patch fixes this by passing the elems value to the add function. Then the
add function can set it before queuing the initial event.

This flag is for legacy drivers only and will go away in the future.

A note regarding commit 5126f259
(v4l2-dev: add flag to have the core lock all file operations):

That commit message suggests that by not taking the core lock for fops
other than unlocked_ioctl all problems relating to AB-BA locking and
mm->mmap_sem are solved. This is not the case.

More work needs to be done by moving the core lock further down into
video_ioctl2. It should only be taken after the copy_from/to_user calls
are done.

The querycap ioctl returned an incorrect version number and incorrect

The reason for that was that video nodes could do vbi activities: that

been resolved. The mxb/saa7146 driver now passes the v4l2_compliance tests.
